Document Summary
Gss worksheet: fill in the following table: A female fruit fly possessing the mutant dominant allele for spots denoted s is crossed with a wild type male. A reciprocal cross is also performed and the following results are observed in the f1 generation for each cross each f1 is comprised of 1000 offspring: 0: define the terms: reciprocal cross, wild type allele, mutant allele: Reciprocal cross: a set of crosses where the parental phenotype for each sex is reversed to test the role of parental sex on the inheritance pattern. Wild type allele: an allele characteristic of the species in a natural breeding population (present in over one percent of the population). The results of the f1 crosses for the first and reciprocal cross are different. If this were an autosomal trait we would observe similar results in the f1 for both crosses.
